How can you reduce the risk of hand-arm vibration when using a vibrating tool?

Use the tool for a shorter time.
Do not grip the tool too tightly.
Wear gloves at all times.
Increase the speed of the tool.

The correct answer is: Do not grip the tool too tightly.

The most effective way to reduce the risk of hand-arm vibration when using a vibrating tool is by ensuring you do not grip the tool too tightly. A firm grip can increase the level of vibration transmitted to the hands and arms, which over time can lead to vibration-related health problems. By keeping a more relaxed grip, you can help minimize the impact of the vibrations experienced during operation, which can subsequently reduce the risk of conditions such as Hand-Arm Vibration Syndrome (HAVS). Using the tool for a shorter time may help decrease exposure to vibration, but it doesn’t specifically address the mechanics of how vibration is transmitted through the grip. Wearing gloves may provide some cushioning, but they do not significantly reduce the actual vibration transmitted to the hands. On the other hand, increasing the speed of the tool would likely increase the vibration levels, which is counterproductive to reducing vibration exposure. Therefore, having a relaxed grip is a direct way to mitigate the risk associated with vibrations.
